LINING-PLUNGER 'FOR OIL-WTELL PUMPS.

To all whom 'it may concern.'

Be it known that we, DANIEL DANInLs and Lr'sLn l. Bunonss, both citizens of the shown in our application for pfitentfiled` September 13, 1909, Serial No. 517,527, in which the lining of the working barrel is made up of a series of sections, and one of the main objects of the present invention is to `provide a device of the character described which will line up the sections of the working barrel.

Another objectof the invention is to provide a device of the character described in which the lining of the working barrel made up of a plurality of sections may be assembled and handled as a unit.

Another object of the invention is to provide a device of the character described which is simple and economical in construction and eliicient lin operation.

In the accompanying drawings which illustrate the invention: Figure 1 is a vertical sectional view vof the lining plunger With the lsections of a working barrel lining assembled thereon. Fig. 2 is a sectional view through the working barrel of an oil well, showingl the manner of Aplacing the lining in the workingbarrel. Fig. 3 is an enlarged 'sectional View of a portion of one of the sections of the lining plunger. Fig. 4 is an inverted plan view of the lining plunger shown'in Fig. 3. Fig. 5 is a plan view of y -the device shown in Fig. 1.

As illustrated in Fig. 2 of the drawing the Worthing barrel comprises an outer casing or shell 1 of cylindrical form, upper and lower collars 2 and 3 respectively screwed thereto, and a lining formed of sections 4 which engage with one another and with the upper and lower members 2, 3. Means are provided at the ends of the sections for interlocking the sections consisting of rings 5 which .tit 'into grooves in the ends of the sections 4 so that the sections are held in alinement between the collars 2 and 3. It is essential that the sections com osin the lininggof the workingebarrel shou d be ined Specification of Letters Patent.

up absolutely7 true so that a smooth surface is presented to the pump piston. This result may be best accomplished by assen'ibling the sections before placing them in the working barrel and for this purpose a lining plunger is used consist-ing ot' a series of tubular sections held together by a clamping rod.

The lower or bottom section is provided with a head 7 screwed into'the end thereof so that the lower edge of the sect-ion G abuts against a Harige 8 on the head. The upper end of the section (3 has its outer edge beveled as shown at. 9 and is provided withl a perforated cap 10 seated upon a shoulder formed within the end of the section. The intermediate sections 11 are similar in form, each section 11 consisting of a tubular body portion having the inner lower edge beveled as shown at 12 corresponding to the top of the adjacent section below. Each section 11 is slotted from the bottom upward as indicated at 13 so that the bottom portion of the section may be expanded as hereinafter described. For the purpose of equalizing the expansion on all sides of the section the bot.- tom of each section is counterbored as indicated at 14. The to of each of the intermediate sections 1l 1s beveled at 15 in the same manner as the lowerinost section and is also provided with a perforated disk 10. The lower part of the uppermostsection 1G is formed identically the saine as the lower portion of the intermediate sections having a beveled inner edge 12 and slots 13. The top of the sect-ion 1G is provided with a head 17 hav-ing a square portion 18, the head being screwed into the section 16 so that the top of the section 16 abuts against a shoulder 19 formed on the head. Screwed into the head 7 in the bottom section G is a clamping rod20 which extends through the hollow sections and through the head 17, the upper end being threaded to receive a'nut 21.

The device is used inthe following manner: As shown in Fig. 1, the sections comprising the plunger are assembled on the clamping rod 20, the nut 21 being arranged so that the sections of the lining plunger are supported on eachother in upri ht position on 'the floor 22, inawhich position the sections forming the lining of the working barrel are slipped down on the lining lplunger, the sections of thelining plunger eing .arranged so that the slotted end of each section engages the lower. end of a lining section and the upperl end of the next scction below at the joint thereof, after which the square portion 18 of the head 17 is moved into engagement with any suitable brace or bracket 23 having a corresponding square slot or opening 24: therein so that the lining plunger Vis prevented from turning. The nut 21 is then tightened against the upper face of the head 17 drawing the two ends of the 'plunger together and expanding the lower end of each of the sections of the plunger due to the beveled ends of the scctions coacting witn each other.

The portion ofl each section of the lining plunger expanded by the above operation alines the sections of the working barrel and clamps them irmly together on the lining plunger. The lining plunger and the sections of the lining of the working barrel thereon are then removed bodily and placed lwithin the working barrel as shown in Fig.

3, with the lowermost section of the lining resting on a shoulder 25 in the lower collar 3 of the workin barrel. The upper collar 2 is then screwe fast to the casing or shell so that the sections comprising the lining are securely engaged between the upper and lower collars of the working barrel after which the nut 21 may be unloosened and the lining plunger removed, leaving the working barrel ready to receive the regular pump piston.

It is understood that the lining plunger may be made longer or shorter as occasion requires by changing the number of sections on the clamping rod, and it is further understood that the lining plunger may be used for lining up and clamping any construction made up of a series oftubular sections. tions of the lining plunger may be varied in length or size or in number to meet the particular conditions for which it is used.

What we claim is:

1. A lining plunger comprising a series of tubular sections having their adjacent Itis also understood that the secends correspondingly beveled and means for clamping said sectlons together.

2. A lining plunger comprising a series of tubular sections having their adjacent ends correspondingly beveled and having their lower ends slotted, and means for clamping said sections together to expand the slotted ends of the sections.

3. A lining plunger comprising a series of tubular sections one above the other, each of said sections having their adjacent ends correspondingly beveled, a head in `the lower section, each of the remaining sections having their lower ends slotted, a head in the upper section, a rod secured in the head in the lower section and extending through the head in the upper section, and means for clamping said sect-ions on said rod to expand the slotted ends of the sections.

f1. A lining plunger comprising an upper tubular section having a head in the top thereof, a lower tubular section having a head in the lower end thereof and a perforated cap in the top thereof, intermediate sections between saidupper and lower sections, all of said sections having their adjacent ends correspondingly beveled, the top section and the intermediate sections each having their lower ends slotted, a perforated cap in the top of each intermediate section, a clamping bolt secured in said head in the lower section and extending through the head in the top section, said 'bolt being threaded, and a nut on said bolt abutting against the top of the head in the upper section to expand the slotted ends 'of the sections.

In testimony whereof, we have hereunto set our hands at Los Angeles, California, this 10th day of June, 1910.
